【摘要】 随着信息技术的发展,数字化地理空间信息资源不断丰富,信息资源共享和存取开放受到越来越多的关注。但由于这些资源产生于不同的行业部门,多数情况是分散管理和存储的,不便于资源的共享与交互。本文在现有的政务信息资源目录服务体系的基础上,研究政务信息资源目录服务体系的基本概念和总体框架,给出地理空间信息资源目录体系的概念,基于LDAP协议建立地理空间信息资源目录服务体系,来实现来自不同部门不同行业的地理空间信息资源迅速获取和共享。
【Abstract】 With the acceleration of the developing of Information technology in current era,not only comes the prosperity of digitalized geo-spatial information resources,but also people shed more light on the sharing and storage of information resources.However,such information has been generated from divergent fields and managed by distributed storing approach,which will bring a great deal of obstacles for the prospect of data sharing and interoperation.The paper focus on the basic concept and main framework of Government Information Resources Directory Service system while referencing the currently GIRDS, proposed the definition of geo-spatial information resources directory system with the construction of prototype system,which aims to the absolute solution of effective retrieval and sharing of geo-spatial information from various fields and different departments.
